Good morning, I am currently using the uart protocol to communicate my Nexys 4 DDR with Matlab, but I have the inconvenience that I need to send signals of more than 8 bits, someone knows how to receive matrices in vhdl by uart (something like the function fread de matlab).
Thank you for your attention

Hello,
I have been struggling for a while now trying to get sound on the ZyBo board. I built images with the OpenEmbedded and Yocto projects where I added the following layers:
https://github.com/emcongiu/meta-zybo
https://github.com/Xilinx/meta-xilinx
I enabled so many recipes that I couldn't remember exactly which ones.
As a test, I also tried the Linaro distro provided in this tutorial: https://reference.digilentinc.com/zybo:zybo:zybotguide
But still no sound card detected.
I really need to work with the audio on this board, how can I enable it ?
Thanks in advance
